build-any-os
Reverse engineer an existing operating system from an ISO and rebuild it ReactOS-style, component by component, until apps written for the original OS run on the rebuild. Use when the user wants to recreate, clone, reimplement or rebuild an OS ("rebuild this Windows XP ISO ReactOS-style", "make an OS that can run Windows apps", "reverse engineer this ISO", "why won't my rebuilt build run notepad"). Covers ISO fingerprinting, sandbox VM labs, API-surface surveys, behavioral specs, clean-room component scaffolding, builds, in-VM app testing and knowledge-base notes.
